桉树是广西主要速生丰产造林树种之一,造林面积已经达到165万hm~2,“十二五”期末将达到200万hm~2,年生产木材3 000万m~3,如此大的采伐量为伐木工作提出了新要求。文章从联合采伐机和油锯的伐木成本进行分析,认为利用联合采伐机可以节约油锯伐木成本的43%,能大大的降低劳动强度,显著提高劳动效率、促进林业现代化建设。
Eucalyptus is one of the main fast-growing and afforestation species in Guangxi. The afforestation area has reached 1.65 million hm 2. At the end of the 12th Five-year period, Eucalyptus will reach 2 million hm 2 and annual production of 30 million m 3 wood. Harvesting sets new requirements for logging work. Based on the analysis of the logging costs of the joint harvester and the chain saw, the article thinks that using the joint harvester can save 43% of the cost of logging sawing, greatly reduce the labor intensity, significantly improve the labor efficiency and promote the forestry modernization.
